Luke 8:33

8:32 Now a herd of many swine was feeding there on the mountain. So they begged Him that He would permit them to enter them. And He permitted them.

8:33 Then the demons went out of the man and entered the swine, and the herd ran violently down the steep place into the lake and drowned.

8:34 When those who fed them saw what had happened, they fled and told it in the city and in the country.
